>From fpc/compiler/options.pas:

  { Set up a default prefix for binutils when cross-compiling }
  if source_info.system<>target_info.system then
    case target_info.system of
      { Use standard Android NDK prefixes }
      system_arm_android:
        utilsprefix:='arm-linux-androideabi-';
      system_i386_android:
        utilsprefix:='i686-linux-android-';
    end;
